I’ve often heard that every once in a while a train won’t crest the launch hill and will rollback, causing the other trains to stop at their respective block brakes. Has anyone ever experienced this personally or observed it from off the ride? I haven’t for sure, I’ve actually never been stacked at all.

I’ve never been stopped on or seen a stop on CS. I’ve never been stacked on it, either. I remember reading about somebody’s backpack falling out of a train and initiating an emergency stop about a year or so ago, but that was an isolated incident. It’s about one of the most efficiently operated coasters I’ve ever seen.
